HYDROCARBON INCANDESCENT LAMP.

SPECIFICATION forming part of Letters Patent No. 730,498, dated June 9, 1903. kApplication filed August '7, 1901. Seria-11H0. 71.264. (No model.)

To a/ZZ whom it may concern.:

Be it known that I, GEORGE WASHINGTON, of New Brighton, in the county of Richmond and State of New York, have invented certain new and usefullmprovements in Hydrocarbon Incandescent Lamps; and I do here# by declare the following to be a full, clear,

and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. My invention relates to an improvement in hydrocarbon incandescent lamps, the objectbeing to provide means for more readily and quickly heating the vaporizing-tube and to simplify and improve the lamps of this general character.

With these ends in view my invention consists in the parts and combinationsof parts, as

will be more fully described, and pointed out in the claims. V

In the accompanying' drawings, Figure 1 is a view in longitudinal section of my improved lamp, and Fig. 2 is a view in plan of the auxiliary burner surrounding the vaporizin gtube.

A represents the vaporizing-tube, provided at its lower end with a removable plug 2, in which the valve--operatin g shaft 3 is mounted.

This shaft 3 actuates the needle-valve/l, which latter passes upwardly through the Vaporizing-tube Al and through the nozzle 5.. The upperend of valve 4 ismade tapering, and this tapering portion, which passes through the nozzle 5, operates to regulate the supply of vapor passing into the commingling chamber or tube 6. This chamber or tube 6 rests on the discharge end of the vaporizing-tube and is provided centrally with an openingfor the passage of the nozzle 5 of said vaporizer A.

Surrounding the tube or chamber 6 is the burner-tube 7, which latter is providedat a point slightly above the upper open end of the coinmingling tube or chamber 6 with a perforated diaphragm S, which latter retards to a certain extent the free upward passage of the mixed vapor and 'air and causes a p0rtion of the latter to descend and pass out through the jet-openings 9, `formed in the lower end of the burner-tube 7. The lower end of this tube 7 is bent inwardly, as shown in Fig. 1, to engage the baseof the commingling or mixing tube 6 at a point above the lower end of the latter, and the shoulder thus formed by bending the lower end of the tube inwardly is provided with the jet-openings 9, above referred to. Passing through the burner-tube and discharging into the comnels or grooves 14, the latter being separated, Aas shown, and in open communication with the central bore 13. The vaporizing-tube A approximately iills the central bore 13. Hence when the tube A is in position each channel or groove is closed Vpractically from top to bottom. rlhe channels or grooves 14 extend throughout the length of thc auxiliary burner 10 and terminate about the outwardly-projectiug heat-retaining flange 17, integral with said auxiliary burner.

Located within the chamber formed by the upwardly-proj ecting dan ge 12 of the auxiliary burner is the conical sieve 15, which operates to spread or diiuse the vapor escaping from the jet-openings 9 and cause the flame therefrom to be distributed equally around the auxiliary burner and into and through the several grooves or channels therein.

Secured to the upper end of the burner-tube 7 is ,the perforated burner-cap 16, through which the vapor issues and on which it is burned under a mantle.

' The auxiliary burner may be utilized with or secured to the vapori'zing-tube, or it may be secured to or integral with the burnertube, or it may be made iudependentof both of said parts.

In the `operation vof my lamp the initial evaporization of 'the oil may be secured by igniting oil or alcohol in a stationary cup around thevaporizing-tube by a torch or by the application of heat to the vaporizing-tube in any other manner. After the vaporizingtube has been heated the vapor escapes through the nozzle 5 and passing upwardly through the commingling-tube 6 draws or sucks in air through the air-pipes l1. The air thus drawn into the commingling-tube becomes thoroughly mixed with the vapor and part of it passing up through the diaphragm S issues through the burner-cap 16 and burns under the mantle. The diaphragm 8, 110W- ever, prevents the free escape of the mixed air and vapor. Consequently the tube '7 beloW the diaphragm 8 becomes filled With the mixed air and vapor and a portion of it escapes through the jet-orifices 9. The air and vapor discharged through the orifices 9 is diffused by the conical sieve l5 and passing through the meshes of the latter is ignited by the torch or other means employed for the initial heating ot the vaporizer and burns in the several channels or grooves lit in direct contact With the thin Wall of the vaporizer. The combustion of the vapor and air Within the channels or grooves 14 quickly heats up the block l0, and the heat from it, together With the direct contact of the flames in the several channels or grooves 14 With the vaporizer, readily and quickly heats the vaporizer A and maintains it at all times at a temperature sufficiently high to vaporize the oil therein.

Having fully described my invention, what l claim as new, and desire to secure by Letters Patent, is-

l. The combination with a burner-tube having a main burner, and commingling-tube surrounded by the main burner and closing an opening in the bottom of the latter, the said main burner being provided in its bottom, around the commingling-tube, with a series oi jet-orifices, of a vaporizer the nozzle of Which projects into the lower open end of the commingling tube, and an auxiliary burner embracing the upper end of the vaporizer immediately Abelow the jet-orifices in the main burner.

2. In a hydrocarbon incandescent lamp, the combination with an auxiliary burner comprising a block having a central bore for the passage of the vaporizing-tube and a series of grooves or passage-Ways open at their ends and also in open communication with the central bore, of a vaporiZing-tube approximately filling the central bore of the auxiliary burner, and a main burner having jet -orifices for discharging vapor to the grooves or channels in the auxiliary burner.

The combination With an auxiliary burner comprising a block having a central bore for the passage of the vaporizing-tube and a series of grooves or passage-vvays open at their ends, of a vaporizing-tnbe approximately illing the bore of the auxiliary burner, and a main burner having jetorifices for discharging vapor to the grooves or channels in the auxiliary burner.

4. The combination with an auxiliary burner comprising a block having an annullar chamber at its upper end, a central bore and a series of grooves or passage-Ways arranged around the bore, a sieve located within said annular chamber and a vaporizer passing through said bore and sieve, of a commingling-chamber to receive the vapor as it issues from the vaporizer, a main-bn rner tube, and jet-orifices from the latter opening into the annular chamber in the auxiliary burner. In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
